bought well over dozen of them over time now regretting it badly
1st most pools are not able to mine on them aswell the apollo version miner
worst still i have 10 fans not working at all or not spinning like they used to- and at current prices be costly to buy and suffer the same results as i did
i even rented all futurebit miners on rentals and i got so many not hashing and being abused by rental admins that the rigs are crap and had my accounts suspended cause running them if i run l3 antminers no problem
this..
i got 8 of the M1s and they mined for over a year and a half with little to no issues..
i used the ltc from the m1s to get 8 m2s and these have been nothing but problems..
they take over 2 amps.. so most USB hubs dont work.. the ones that do only work with 2 or maybe 3.
they constantly disconnect and stop mining.. so you have to keep rebooting them.. i made a script to do it automatically but still sometimes the whole rig needed powered off and back on.
some pools they wont even connect to.. they just time out and sit idle.
i paid over 6 LTC for these, plus almost $100 in usb hubs and they have been sitting on my desk for months.. collecting dust :/
like a month after i got these, he announced a pod.. i really wish i got one of those instead..
